To all whom it may Concern Be it known that we, VILLIAM L. FRANns and VILLIAM O. Haskins, citizens of the United States, residing at Evansville and Owensboro, respectively, in the counties of Vanderburg and Daviess, respectively, Vand Statesof Indiana and Kentucky, respectively, have inventednew and useful Improvements in 'iIotor-Cultivators, of which the following is a specification. c

This invention relates to motor cultivators and it consists in the novel features hereinafter described and claimed.

VAn object of the invention is to provide a motor propelled cultivator with simple andeflicient means for adjusting the soil engaging members thereof with relation to each other and also with relation to the frame of the cultivator. f Y

A further object of the invention is to provide means such as indicated which may be manipulated whereby the cultivator may be transformed from a soil stirring implement to a harrow or pulverizer. f

Vith these objects in view the cultivator comprises a frame mounted on wheels.v An engine is mounted upon the frame and is operatively 4connected with the other two supporting wheels of the frame.v Beams are pivotally connected with the frame and soil engaging members are pivotally connected with the beams. Lever mechanisms are provided upon the frame and are operatively connected with the soil lengaging members to adjust the same and a lever is adapted to be used to adjust all of the soilv engaging members simultaneously. Other lever mechanisms are mounted upon the frame and may be used for raising and lowering'the soil engaging members.

v.In the accompanying drawings z-Figure 1 is atop plan view ofthe cultivatorg'Fig. 2 is a side elevation of the same. The other figures are detailed views'of the several features thereof.

The cultivator comprises a frame 1 which includes a -front arch axle 2 and a rear arch axle 3. yDirigible wheels 4 are pivotally mounted at the ends of the arch axle 2 and supporting wheels 5 are journaled at the i ends of the axle 3. An operators seat 4 is mounted upon the frame 1 and -a steering shaft 5 is journaled in the frame 1. The

shaft 5 is provided at its upper end with are provided with a wheel 6 which may be used by one occupyingv the seat 4 for turning the shaft 5. Rods or chains 7 are connected with the lower portion of the shaft 5 and the spindles 8 upon which the'wheels 4f are journaled. The spindles 8 are pivotally mounted at the ends of the axle 2.

An engine 9, preferably Vof the hydrocarbon type, is mounted upon the forward portion of the frame 1 and is provided upon its shaft with a sprocket wheel 10. A shaft .1 is journaled for rotation at the forward portion of the frame 1 and carries a sprocket wheel12. A sprocket vchain 13 is trained around the sprocket wheels 10 and 12 and is adapted to transmit rotary movekment from the engine 9 to the shaft 11.

Sprocket wheels 1% are mounted upon the ends of the shaft 11 and sprocket wheels 15 are fixed to the sides of the wheels 5. Sprocket chains 16 are trained around the wheels 14 and 15 and are adapted to transmit rotary movement from the shaft 11 to the wheels 5 whereby the implement is propelled over the ground.

A shaft 17 is carried at the forward por-A tion of the frame 1 and beams 18 are pivotally connected at their forward ends with the said shaft 17. Spindles 19 are pivotally mounted at the rear ends of the beams 18 and soil engaging members 20 are carried by the said spindles. In the present instance the saidY soil engaging members 20 are in the form of disks although shovels orV points may be substituted for the disks if desired.

A. shaft 21 is journaled upon the frame 1 and levers 22 are pivoted upon the shaft 21. Rods 23 pivotally connect the working ends of the levers 22 with the free ends of the spindies 19. Segments 24 are mounted upon the frame 1 adjacent the levers 22 and teeth. The said leversY 22 carry spring pressed pawls 25 which are adapted to engage the teeth of the segment 24 and hold the levers 22 at adiustedpositions. A lever 2,6 is fixed to the shaft 21 and may be used for turning the said shaft and the levers 28 and the segments 24C mounted thereon. A dentate segment 27 is mounted upon the frame 1 adjacent the lever 26 and the said lever 26 is provided with a spring pressed pawl 28 which is adapted to engage the teeth of the segment 27 and hold the lever 26 at an adjusted posi- A tion. Levers 29 are mounted uponthe rear or the said means lmaybe manipnlated -to lower the .said soil v.engaging `members in Contact withthe soil. Bymanipulating the levers 22 the soil .engaging .vmembersQO may be positirned at aY desired angle with relation to the lineroiY draftrof the cultivator andby using the Vsaid levers independently Y Y the said soil engagingl members 20 maybe ladjusted `indepe'ndentlyof each other. By manipulating ythe lever 2 6 all Vof lthe soil engaging members 2O `may be adjusted simultaneously. The soil engaging members 20 maybe disposed parallel with the line of Y draftof the cultivator or they maybe dis-I posed at anydesiredange sothat theyma'y oastMLjhe soil to oneside or thevother. Y

`Having described the invention What isclaimed is Y vA oultivatcr comprising' a frame, beams pivotally connected With the frame, vspinother, earth Working implements carried by the spindles, means VVfor adjusting the spin-V dlesupon their .pivots independentlyl of each other, .and meansV for adjustingthe spindles simultaneously :to vary :the anglezof tlieearth working implements :With'irel-a-tioh `to lthe beams; s a e Vlntestimony whereof We affix our slgnatures in presen'cefofftwo Witnesses;
